BYRON SLOPER, OF NEW YORK, N. Y.

LOCOMOT IVE-FURNACE.

StPECIl-"ICATION forming part of Letters Patent No. 298,247, dated May 6, 1884.

Application filed February 15, 1884.

T0 ail whom it may concern.-

Be it known that LBYRoN SLOPER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Locomotive Furnaces, of which the following is a specification, refer-. ence being had therein to the accompanying drawings.

This invention has for its objects to providean improved furnace and a system of combustion to be employed in connection therewith, whereby the fuel will be so perfectly consumed initially that practically no smoke, sparks, or cinders will be produced, and the full .and effective heating-power of the fuel will be utilized, as more fully hereinafter set forth.

My invention further relates to certain improved devices for supplying the steam and air to the furnace, the same consisting in a distributer having a perforated diaphragm located within it, for the purpose of commingling the steam and air in a heated state, as more fully hereinafter specified.

My invention further consists in a distributer having a perforated diaphragm, for the purpose of checking the direct influx of cold air into the furnace and causing the air to be diffused and retained in a chamber until properly heated, and finally directed into or over the surface of the fuel, in order to insure the thorough combustion of the same and prevent the formation of smoke, cinders, or other imperfect products of combustion.

In the usual furnaces, and under the here tofore-existing systems of combustion, the fuel has been subjected to an intense heat at the (No model.)

form of smoke, by rendering the initial combustion thorough and complete, as will be more fully hereinafter specified.

In carrying out my invention I have found by practical experience that the steam and hot air should be delivered into the fuel at an angle 5 of about thirty degrees, and that it should strike the fuel directly beneath thefire-bridge, so as to cover the whole surface of the fuel in such manner that the steam may come into instantaneous contact with the fuel at the most highly heated part, in order that the steam may be thoroughly decomposed. I have also discovered that, when the initial draft meets the fuel at such angle, the resultant draft caused by the consumption of the fuel is not 6 retarded, but, on the contrary, is increased. The .above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which view'of a locomotive-boiler, showing my invention applied thereto. Fig. 2 represents a sectional view, in detail, of the diffuser or distributor, showing the same attached to the water-legs of the boiler. Fig. 3 represents a front 7 5 view of the diffuser or distributer, and Fig. 4

a rear view of the distributer detached.

The letter A indicates the walls of the furnace, which may be constructed in the ordinary or any improved manner. In the prescut instance, however, I have shown an ordinary locomotive-boiler. At each side of the door, or at any other convenient portion, the walls or water-legs are pierced, forming openings B, in which are set the thimbles O, for the 8 5 purpose hereinafter described.

The letter D indicates my improved distributer. This consists of a bell-shaped or a concavo-convex shell having a curved diaphragm, E, which is perforated, as shown. 0 The said diaphragm is provided with an open ing, F, at its center, through which projects the end of a steam-pipe, G, leading from the dome or dry-steam space of the boiler. The said shell is provided with lugs H, which are 5 adapted to set over ears located on the inner walls of the furnace, the said ears being provided with slots, through which may be driven Figure 1 represents a longitudinal sectional 7o pins to hold the shell in place. the shell is provided with an oblong slot, M, through which the steam and heated air are discharged into the furnace. In order to heat the incoming cold air and to prevent the condensation of the steam, which induces the current or currents of air, the shell or distributer is provided at its lower edge with a series of apertures, N, through which an induced current of hot gases is drawn in directly from the fuel, which, commingling with the air in the chamber previous to its meeting the steam, is still further heated and diffused by passing through the perforated diaphragm, so that upon commingling with the steam in the chamber a it will not cause condensation, and will allow the steam to be instaneously decomposed upon striking the fuel. I prefer to deliver the steam in a broad, thin, fan-shaped stratum, so as to act like a mat upon the surface of the fuel and prevent the exhaust from lifting the einders and carrying the same into the fines, thereby insuring their combustion in the firebox. By thus effecting a perfect and thorough combustion of the fuel, initially, and preventing the formation of smoke, cinders, and sparks, the full and effective heating-power of the fuel is utilized, and a large saving of fuel is effected.

Having thus fully described my invention,

The front of I what I claim, and desire to secure by Letters Patent, is

1. A distributer for distributing hot air and steam for the purpose of surface combustion, consisting of a bell-shaped or concavo-convex shell having a perforated diaphragm and an opening through which the steam and air may be injected into the furnace, substantially as specified.

2. The distributcr or diffuser consisting of a bell-shaped or concavo-convcx shell having a perforated diaphragm and a series of perforations at its lower edge, whereby the induced cold air is heated by an induced current or currents taken directly from the furnace, substantially as and for the purpose specified.

3. The distributer or diffuser consisting of a metallic shell having an elongated opening in front and a perforated diaphragm dividing the easing into two chambers, in which the air and heated products of combustion are induced, diffused, and commingled previous to coming into contact with the steam, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
